, learning to live with it too! But still hoping that they find the right solution. If that rattling sound goes away, owners would be totally satisfied.
I've been figuring this since March. Not really an issue as confirmed by my dealer but an annoyance. After fueling with high octane gas, the noise still exists occasionally. The very recent updates I have is when few weeks back, I had it checked up with my dealer. A Korean Engineer confirmed that the sound is tolerable.
By now, I know when the sound will come out. The noise goes away when
1. Rev 2000 RPM
2. Make careful turns
3. Maintain a constant speed
